1. An active antenna array for a mobile communications network comprising:

  • a plurality of antenna elements for relaying first protocol radio signals and second protocol radio signals;

    at least one first splitter, coupled to an individual one of the plurality of antenna elements, adapted to forward at least one of at least one individual first protocol receive signal and at least one individual second protocol receive signal in a receive direction from an individual one of the plurality of antenna elements;

    at least one amplifier, coupled downstream to the at least one first splitter, for amplifying at least one of the at least one individual first protocol receive signal or the at least one individual second protocol receive signal;

    at least one first coupler coupled to the at least one amplifier, in the receive direction downstream of the at least one amplifier, the at least one first coupler being coupled to at least one second splitter and being adapted to forward, on a first path, the at least one individual first protocol receive signal to the least one second splitter, the at least one first coupler being further coupled to a second protocol receiver and being adapted to forward, on a second path, the at least one individual second protocol receive signal to said second protocol receiver; and

    the at least one second splitter located in the receive direction downstream of the at least one coupler and coupled to a passive feeder network or cable, adapted to forward the at least one individual first protocol receive signal in the receive direction to said passive feeder network or cable and further adapted to forward at least one individual first protocol transmit signal in a transmit direction along a transmit path.
